HUMIDIFYING sYs'rEir.

To all whom 'it mag concern: I Be it known that we, EDWARD MAXWELL and HERBE T J Arias PAGE, both of the city of Montreal, Province of Quebec, Canada, have invented certain new and useful Improvements in Humidiiying Systems; and we do hereby declare that the following is a full, clear, and exact description of the same. I p

Our invention relates particularly to humidifiers for use in buildings'although it may be applied-to other uses without departing from the spirit of our invention, and it has foiits object to provide a device of this type WhiCllWill automatically regulate the humidity of a chamber to a predetermined degree, and, further ob.- jects of the invention are to render the device noiseless ,in its operation, and adapt the same to diffuse an antiseptic substance or'a p'erfumethrough such chamber.

The invention maybe said briefly to consist ofa vaporizing chamber'and a retort included in a closed circuit and presenting a vapor receptacle outside of the heater while the retort is located within the latter, and means is provided toestablish a water level within the circuit. 'A controller for the water supply is located in the chamber to'be humidified and is adapted to be afmospheric humidity.

fec ted by the humidity of the atmosphere, and comprises, preferably a' strip of wood having one side coated with a waterproofing substance and its other side treated with calcium chlorid or other substance adapted to render the same more susceptible to variations in the at- For full comprehension, however,' of our invention reference must be had to the accompanying drawings forming a part of this specification in which simiar referen'ce characters indicate the same parts and wherein hate, the retort and yapori zing-chamber being shown ,pa'rtly sectional view; Fig. 2 is an enlarged vertical sectional view of the vaporizing chamber; Fig. 3 is an enlai-ged elevation partly in section of the means for controlling the water supply to the retort; Fig. 4 isa detail enlarged elevation of the retort, and 5 is a horizontal sectional view thereof. r r

The steam generating apparatus of our improved hu- I finidif yingsystem coniprisespreferably a retort and-a vaporizing chamber included in a closed circuit. The- 4 having both ends closed"and located within the fire its end in close proximity to the seLqlocated outside of the fire chamber andwith its top 1'55 I 'point a short distance below the top thereof while the retort consists preferably of a-vertically arranged tube b chamber of the furnaceAKo other heat generator) with grate B and its lower portion covered by the fire bed 0.

The vaporizing chamber consists preferably of a-vesabove the level 'of the retort. A pair of pipes d and e extend from' the top and bottom. respectively ofthe retortthrough openings in the wall of the furnace, and thepipe. d is connected to the vaporizing vessel at a Specification of Letters Patent. -.Application filed March 10,1906. Serial No. 305,401.

Patented July 9, 1907 pipe e is connected to and communicates with the bottom of such vessel; The top of this vaporizing vessel is closed by a hermetically sealed co'ver f from the center of which a steam pipe 9 leads, and an inverted cup h within the upper end of the vessel has its lower end located in an annular trough 'i kept constantly filled by the water of condensation; while a spindlej of diminutive cross-section projects from the center of the cup into the lower end of the pipe 9 and localizes such cup. The wall of the latter is formed with perforations Io. Water is fed to the retort and vaporizer by a pipe m connected to the pipe e, and the desired level (slightly above the pipe d) ismaintained by an overflow pipe n. Our improved device whereby the humidity of a chamber controls the water supply, consists, preferably,

of a frame supporting means the shape whereof is changed by changes in the humidity of the chamber,

(preferably hard wood dried to the usual outside atmospheric degree of humidity) hasone side coated with a waterproofing mixture. One'end of this strip is secured by a screw s to the frame plate p and the .other end thereof is free, such strip being arranged with.

its waterproofed side towards such frame plate p.

A block, t, formed with an exteriorl y screw-threaded nipple 'u. is secured to the frame plate, by having such nipple screwed throilgh an opening therein. This block is bored, to present a vertical passage 2 witha flared mouth 3, and an angular passage 4 with its upper end terminating in a flared mouth 5, the other end of the latter passage terminating in the interior of the nipple which forms a continuation thereof; while atransverse partition 6 constitutes the adjacent side walls of the flared mouth and in; top edge is sharpened to a knife edge. p

l A pipe 7 of diminutive bore leads from any available water supply to the top of the interior of the supporting frame where it is formed into a coil 8 to increase the resiliency thereof and its end 9 is extended. down over the strip 2' of wood upon the freeend of which it bears,

and is retained indifferent positions (according tothe curvature of the strip) over the flared mouths above mentioned.

A pipe 10 leads from the vertical passage 2. to the upper end of the pipe m, and a pipe 12 leads from the nipple 'u. to any available waste pipe, or other waste discharge not shown; while the upper end of pipe 9 is connected to the upper end of an inclined pipe 13 the lower end whereof is connected by an elbow 14 to a pipe 15 the upper end whereof terminates in a grating 16 located at any suitable point in the chamber to be humidified. "The elbow l4 constitutes a receptacle for the water of condehsation from pipes and 13 and a drip pipe 17 leads therefrom to the pipe m.

The degree of humidityin the atmosphere causes the sides of the strip of wood not waterproofed to contract water thus dropped finds its way to the heated retort where it is immediately converted into steam which rises to the grating 16, and as the water continues to be supplied it gradually reduces the temperature of the retort and fills the latter and the chamber 0 to 'the'level of the overflow n, the steam meanwhile finding its way through theperforations in the inverted cup I: (which acts as a muffler) to the pipes g, 13 and 15 and the grating 1 An adjustment screw enables the normal position of the strip to be varied, and a damper controlled draft duct B affords a means for constantly maintaining a good fire beneath the retort.
